Transformer insulation regeneration and drying in online mode

Emir Šišić ; ArcelorMittal

Abstract

Transformer insulation consists of liquid (mineral oil) and solid (cellulose) parts. The influence of temperature, oxidation and moisture degrades the insulation, creating acids and sediments that negatively affect its characteristics. While there are different methods of insulation renovation, this article will present regeneration and drying in online mode, which is one of the best methods that significantly extends the life of the transformer.
